The fundamental difference between wired and wireless technologies resides in the physical channel. The unique features of wireless propagation such as reflection, refraction, and shadowing result in various channel impairments including multi-path fading, path loss, and doppler frequency, making it very challenging for high-speed information delivery over the wireless channel. Furthermore, the time-varying nature of wireless media poses new design challenges for wireless networks, since the existing Internet protocols were developed based on the assumption that all packet losses are caused by network congestions, which is no longer the case in the wireless environment.
In PSS, an RTCP extension is standardized so as to support packet retransmissions for RTP applicable to unicast and multicast groups. 14 Introduction In , the protocol stacks and the end-to-end architecture of a video broadcast system over WIMAX are introduced. 4, the MBS (multicast/broadcast service) server at the controller side handles coding/transcoding, RTP packetization, mapping video channel ID to multicast connection ID (CID), shaping and multiplexing, encryption, FEC coding, constructing MBS-MAC-PDU for transmission over WiMAX PHY/MAC, burst scheduling and allocating OFDMA data region for each MBS-MAC-PDU.
